The object of the present invention to provide a shoemakers jack which permits the-shoe last to.be easily and quickly ad justed to varying positions, so as to render the part of the shoe to be worked upon more accessible.

-Another object of the invention is to provide a shoemakers jack which, while 09.- pable of many adjustments, isof simple and dura le construction.

With these and other objects in view, the

invention consists of certain novel features of construction as'hereinafter described and pointed out in the claims.

In the drawings employed for illustrating the embodiment of the invention :Figure 1 is a side elevation thereof, showing one of its adjustments in dotted lines. Fig. 2 is a top view illustrating, by circular dotted lines, the rotary adjustments permissible of the shoe last and the jack standard independently of each other. Fig. 3 is a vertical sectional view through the center of the jack base. Fig. 1 is a fragmentary view, partly in section, showing connection between the standard and swinging arm. Fig. 5 is a top view of one end ofthe swinging arm, and Fig. 6 is an edge view of a strap tightening lever.

Referring now more particularly to the accompanying drawings, the reference character 10 represents a base member, having a vertical bore 11 through its center and a clamp screw 12 in the side thereof. The' standard 13 has a reduced lower end 14,

which passes downwardly into the bore of the base, and a shoulder 15 adapted to rest upon the base; or, as shown in the drawings, upon a washer or washers 16, interposed between the base and the shoulder for the purpose of adjusting the height of the jack to suit the workman. As mounted, the jack may be rotated on its base and the shoe last adjusted to the desired position, the largo dotted circle in Fig. 2 showing the sweep Specification of Letters'latent.

.of the last when acomplete turn of the standard is made. The standard maybe looked against rotation by manipulation of the clamp screw 12.

The upper end of the standard. 13 termi- Hates in a head 17, havin spaced walls 18 between which one end 0 a swinging arm 19 is disposed, a pivot bolt 20 being passed through corresponding apertures in the arm.

and walls, and a nut, 21 applied to 'the threaded 'end'of the bolt, which latter has a hand wheel on the opposite end thereof, as

indicated at 22. The end of the swinging arm is designed to snugly fit between the walls of the head, but sufliciently loose so as to permit the arm to freely swing on its pivot, the close fit being desirable so that a slight drawing together of the walls by turning the pivot bolt will firmly clamp the arm against movement. The arm is rounded on its lower edge, as at 23, so as to permit sameto turn on its pivot without interfering with the bottom of the head, while the lower and end edges of the arm are adapted to rest on the head bottom, and thus limit the movement or swing of the arm.

The free end of the swingingarm 19 is cylindrical in formation, and has ears 24.

formed integral therewith and in parallel relation, the cylindrical member, hereinafter referred to'as the s lit head 25, being split its entire length an at a point between said ears. A screw bolt 26 engages threaded Y apertures in said ears for the purpose of drawing the ears together and closing the split so as to effect a binding engagement between the head and the last supporting post 27, the lower end of which extends nto the head. A screw 28 is inserted through the head 25, the end thereof projecting into a circumferential groove 29 so as to hold the post. against lengthwise movement and at the same time permit rotation. thereof. 1

The post 27 is provided. with a tapere upper end and the shhe'last 30 has a socket fitting over said tapefiedg end. A lever 31 s pivoted to a ring 32, the latter being split and fitted into a shallow groove (not shown) in the post, and the ends connected by rivets 33. The ring may thus be turned 1n ts seat, and the lever, which is used for drawlng the strap 34 taut in order to hold the shoe upon the last, can be shifted to either the top or lower side of the last supportingpos't, when in the position shown by dotted lines in Fig.

l.- The endless strap 34 passes through an g stationary, and that thelatter, or the jack opening 35, in theflever; and when the latter is pressed down against the post to tighten the strap over a shoe on the last, the end thereof will be over itspivotal center and fife-tension of the strap will hold same in v v v It will be seen from the foregoing description, that the shoe last and the jack standard aneso-niounted. that the former may be turned 01 rotated While the latter remains asa' whole be bodily turned upon its base, th two independent movements or nathjofroetion being-indicated by the large and...sinalldottedcircles shown in Fig. 2. The last may eke be s ung so as to ass-"me a vertical position, as sl mn in Fig. 1, and as the same may equally as well be rotated while in this position, it is evident that the rangewof adjustments that may be made is such as to meet every requirement necessary .to render every part of a shoe mounted thereon readily accessible, thus effecting 2.

saving oftime and labor. The means permitting vertical adjustment of the jack, so

as to obtain thedes-ired height for workmen of different staturyis also an important and 4 is claimed, is-

In a shoemakers jack, the combination of a last-supporting post adapted to have a last mounted upon one end thereof, a ring rotatably mounted upon the post, an arm projecting radially from said ring, a clampinglever pivotally connected at one 811:1 with the outer end of the arm, and a last-clamping strap connected medially with the lever and adapted to pass around alast mounted upon the post.

In testimony whereof I affix my signature.
